目的了解发达国家医学生器官捐献意愿研究的目的、结果、障碍因素和解决对策。 方法以主题词和自由词联合的方式对PubMed、Web of Science、Ovid MEDLINE、Ovid EMBASE(Excerpta Medica)、EBSCOhost Complete和Cochrane Library等已发表文献数据库,以及灰色文献数据库York Centre for Reviews and Dissemination、Open Grey、ProQuest Dissertation and Theses和Mednar进行系统、全面地检索,并采用Arksey和O′Malley提出的范围综述框架进行文献资料整合。 结果共纳入17项发达国家医学生器官捐献意愿研究。研究背景主要为医学生未来对于公众器官捐献有着重要影响。研究结果表明,大多数医学生器官捐献意愿性良好,但不同亚组的研究结果不一;其最主要的障碍因素为医学生器官捐献相关知识的缺乏;解决对策主要为施予系统化、结构化和可评价的教育课程。 结论21世纪以来发达国家医学生器官捐献意愿研究方兴未艾,其研究的多层面、多角度以及揭示的问题、寻求的解决对策,可对我国现阶段医学生器官捐献的研究提供一定参考。 相似文献
Cancer incidence and mortality are increasing globally, leading to its rising status as a leading cause of death. The Go-Ichi-Ni-San (GINS) complex plays a crucial role in DNA replication and the cell cycle. The GINS complex consists of four subunits encoded by the GINS1, GINS2, GINS3, and GINS4 genes. Recent findings have shown that GINS2 expression is upregulated in many diseases, particularly tumors. For example, increased GINS2 expression has been found in cervical cancer, gastric adenocarcinoma, glioma, non-small cell lung cancer, and pancreatic cancer. It correlates with the clinicopathological characteristics of the tumors. In addition, high GINS2 expression plays a pro-carcinogenic role in tumor development by promoting tumor cell proliferation and migration, inhibiting tumor cell apoptosis, and blocking the cell cycle. This review describes the upregulation of GINS2 expression in most human tumors and the pathway of GINS2 in tumor development. GINS2 may serve as a new marker for tumor diagnosis and a new biological target for therapy. 相似文献
Although lactation mastitis (LM) has been extensively researched, the incidence rate of LM remains a salient clinical problem. To reduce this incidence rate and achieve a better prognosis, early and specific quantitative indicators are particularly important. It has been found that milk electrolyte concentrations (chloride, potassium, and sodium) and electrical conductivity (EC) significantly change in the early stages of LM in an animal model. Several studies have evaluated EC for the detection of subclinical mastitis in cows. EC, chloride, and sodium content of milk were more accurate for predicting infection status than were other variables. In the early stages of LM, lactic sodium, chloride, and EC increase, but potassium decreases. However, these indicators have not been reported in the diagnosis of LM in humans. This review summarizes the pathogenesis and the mechanism of LM in terms of milk electrolyte concentration and EC, and aim to provide new ideas for the detection of sub-clinical mastitis in humans. 相似文献
